+For example, build on macOS:
+```shell

   auto-route: true # auto set global route
 ```
-It's recommended to use fake-ip mode for the DNS server.
-
-Clash needs elevated permission to create TUN device:
-```sh
-$ sudo ./clash
-```
-Then manually create the default route and DNS server. If your device already has some TUN device, Clash TUN might not work. In this case, fake-ip-filter may helpful.
-
-Enjoy! :)
-
-#### For Windows:
-```yaml
-tun:
-  enable: true
-  stack: gvisor # or system
-  dns-hijack:
-    - 198.18.0.2:53 # when `fake-ip-range` is 198.18.0.1/16, should hijack 198.18.0.2:53
-  auto-route: true # auto set global route for Windows
-  # It is recommended to use `interface-name`
-  auto-detect-interface: true # auto detect interface, conflict with `interface-name`
-```
